Committee GEL/86, Fibre optics, to Subcommittee GEL/86/2, Fibre optic
interconnecting devices and passive components.
A list of organizations represented on this committee can be obtained on
request to its secretary.
This publication does not purport to include all the necessary provisions of

Dimension AA is given for plug endface when not mated. It is given for a finished plug endface after all
polishing. The ferrule is movable by a certain axial compressing force, with direct contacting endface, and
therefore dimension AA is variable. The ferrule compression force shall be 5,0 N to 6,0 N when the optical
datum target, dimension AA is moved to the range 6,0 mm to 6,35 mm. Forces are for buffered fibre only;
different cord constructions can result in higher forces, see IEC 60794-2-50.

b

These dimensional requirements apply to the finished ferrule, after all polishing procedures have been
completed.

c

Dimension BF is the radius of the polished ferrule end face.

Dimension AM is defined as an angle between two planes: One plane, plane A, passes through the axis of the
ferrule and the axis of symmetry of the key of the angled endface connector plug. The other plane, plane B,
passes through the axis of the ferrule and the plane normal to the angled PC reference plane.

c

These dimensional requirements apply to the finished ferrule after all polishing procedures have been
completed.

Dimension BI is the radius of the polished ferrule end face.
